Substrate treatment apparatus, method of transferring substrate, and non-transitory computer storage medium

Abstract

A coating and developing treatment apparatus includes a substrate transfer mechanism; and a defect inspection section. A transfer control part controls transfer of a substrate. A defect classification part classifies a defect based on the state of the defect. A storage part stores a transfer route of the substrate by the substrate transfer mechanism when the substrate has been treated by treatment sections. A defective treatment specification part specifies, based on a kind of the defect classified by the defect classification part and the transfer route of the substrate stored in the storage part, a treatment section which is a cause of occurrence of the classified defect, and judges presence or absence of an abnormality of the specified treatment section. The transfer control part controls the substrate transfer mechanism to transfer a substrate bypassing the treatment section which has been judged to be abnormal by the defective treatment specification part.
